Abstract
Abstract An integrally formed, one-piece, generally rectangular, plastic container particularly adapted for holding medicines is disclosed. The container includes a generally rectangular bottom section which is connected to a rectangular top section by means of an integrally formed, flexible, plastic hinge at the rear of the two sections. In the closed position, the top section overlies the bottom section and latch means lock the two sections together. The bottom section has a planar bottom wall, two opposed, upturned sidewalls, an upturned front wall, and an upturned back wall, all of which are integrally formed and connected to each other. The top section has a planar top wall, two downturned sidewalls and a downturned front wall, all of which are integrally formed and connected to each other, and a downturned back wall integrally formed and connected to the top wall. The thickness of the container at the connection of the downturned back wall and the top wall is reduced. Also the downturned back wall and the top wall are joined so as to form an obtuse angle with each other. The container requires that equal pressure be applied to the rear corners thereof in order to disengage the latch means. The container provides a substantially childproof safety closure for tableted medicines such as aspirin, laxatives, cold tablets, prescription drugs, etc.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
255 words
In an integrally formed, one-piece plastic container having a bottom section and an overlying top section hinged to said bottom section; said bottom section being characterized in that it has a planar bottom wall, two opposed, upturned sidewalls, an upturned back wall, and an upturned front wall, all of which are integrally formed and connected to each other, said upturned front wall carrying top latching lug means; and said top section being characterized in that it has a planar top wall, two opposed downturned sidewalls, a downturned front wall, all of which are integrally formed and connected to each other and a downturned back wall integrally formed and connected to said top wall, said downturned front wall carrying bottom latching lug means for engaging said lug means on said upturned front wall of said bottom section to latch said top section to said bottom section; the improvement which comprises: said downturned back wall and said planar top wall being connected one to the other to form an obtuse angle therebetween and said planar top wall and said downturned back wall are connected by flexing joint means having a web of plastic material with a thickness of less than one-half the thickness of said back wall and said planar top wall whereby said flexing joint means allows said planar top wall to move forward upon application of downward pressure to the two rearmost corners of said top section so that said top and bottom latching lug means will disengage to allow said container to be unlatched.
Claim 2
Dependent Claim
255 words
In an integrally formed, one-piece plastic container having a bottom section and an overlying top section hinged to said bottom section; said bottom section being characterized in that it has a planar bottom wall, two opposed, upturned sidewalls, an upturned back wall, and an upturned front wall, all of which are integrally formed and connected to each other, said upturned front wall carrying top latching lug means; and said top section being characterized in that it has a planar top wall, two opposed downturned sidewalls, a downturned front wall, all of which are integrally formed and connected to each other and a downturned back wall integrally formed and connected to said top wall, said downturned front wall carrying bottom latching lug means for engaging said lug means on said upturned front wall of said bottom section to latch said top section to said bottom section; the improvement which comprises: said downturned back wall and said planar top wall being connected one to the other to form an obtuse angle therebetween and said planar top wall and said downturned back wall are connected by flexing joint means having a web of plastic material with a thickness of less than one-half the thickness of said back wall and said planar top wall whereby said flexing joint means allows said planar top wall to move forward upon application of downward pressure to the two rearmost corners of said top section so that said top and bottom latching lug means will disengage to allow said container to be unlatched.
